<em>If a drop of dishwashing detergent is added near it, the paperclip most likely will;</em>
Soap is a surfactant that disrupts the intermolecular forces of water making the paperclip sink.
<u>The paperclip is able to float on the surface of water due to its surface tension. </u>
<u>When soap is added to water, it reduces the surface tension. Soap disrupts the intermolecular forces that hold the molecules on the surface tightly like a film. </u>
<u>Thus, the paperclip sinks into the water.</u>
Answer:
Milk boils at about 212 F (100 c)
Explanation:
A physical property is a property in which a chemical change is not nessecary to undergo to know about.
Since all the other options require a chemical change to know, they are not physical properties.
The third option is a physical property because it does not require a chemical change to know.
Before Rutherford's discovery, the accepted atomic model was J. J Thompson's Plum Pudding Model. According to J.J Thompson, the atom is composed of negatively charged particles. They were then called 'corpuscles', but now known to be electrons. Outside of this atom, surrounds a cloud of positively charged electrons to balance out the charge of electrons, which makes the atom neutral. The 'plum' were the electrons, whereas the 'pudding' were the protons.
Through Rutherford's gold foil experiment, he disproved J.J Thompson's theory. Rutherford was very interested in studying the behavior of x-rays, which was then recently discovered by Curie. When he shot a beam of alpha particles (particles with 2 neutrons and 2 protons, or the Helium atom) toward the gold foil, the particles were deflected by a slight angle. He then theorized that these deflections were due to the existence of a dense nucleus inside the atom.
Following Rutherford's discovery of the nucleus, Niels Bohr theorized the planetary model of the atomic structure. According to him, the atom is like a solar system wherein the Sun is the nucleus and the planets are the electrons orbiting around it. The electrons and protons move this way because they are influenced by an electric force due to the difference of their charges.
Answer: 7s
Explanation:
The order of the reaction is 2.
Integrated rate law for second order kinetic is determined using the formula
1/[At]=1/[Ao] +kt
But, [Ao] is the initial concentration = 1.50 mol/L
And [At] is the final concentration = 1/3 of initial concentration =1/3×1.5 = 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Using the formula
1/0.5=1/1.5+0.2t
Collecting like terms
1/0.5-1/1.5=0.2t
LCM = 1.5
3-1/1.5=0.2t
2/1.5=0.2t
Multiply both sides by 1/0.2
2/1.5×0.2=t
2/0.3=t
t=6.66s
t=7s
<u>Answer:</u> The new volume will be 
<u>Explanation:</u>
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(at constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the new volume will be
